I built a free developer tools site that works entirely in your browser

The article describes CodeToolkit, a free website offering 14 developer tools that operate entirely within the user's browser without requiring login, tracking, or server interaction. The creator built the site out of frustration with other tools that demand sign-ups or display ads for basic tasks like decoding JWT tokens or formatting JSON. The site is designed for speed, works offline, and the developer plans to add more tools weekly based on user suggestions.

Every developer has been there. You need to quickly decode a JWT token or format some JSON. You Google it, click the first result, and boom — "Sign up to continue." Or worse, "Watch this ad to see your result." I got tired of it. So I built my own. CodeToolkit is a collection of 14 free developer tools that run entirely in your browser. No login. No tracking. No server. You paste your input, you get your output. That's it.

Nobody wants to wait for React to hydrate just to encode a Base64 string. Planning to add more tools every week. Some ideas: What tools do YOU wish existed? Drop them in the comments — I'll build them. If this helped you or you find yourself using it, share it with a dev friend who's tired of sign-up walls too.
